Parts of handheld guns have been found at a North Yorkshire battlefield which saw one of the bloodiest conflicts of the War of the Roses.

A metal detectorist unearthed the fragments of the guns, thought to date back to the 15th Century, at the site in Towton, near Tadcaster.

The find contradicts the idea that guns were only used in that period of history to attack castles.

Experts say it sheds light on the use of guns by troops in medieval battles....
